WINDMILL.

SPECIFICATION forming part of Letters Patent No. 274,261, dated March 20, 1883.

Application filed J annary 30, 1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES D. BowLUs, of Ohio, in the county of Bureau and Stateof Illinois, have invented a new and Improved Windmill, of which the following is a full, clear, and exact description.

My invention consists of the windmill mounted on a vertical tube that is bent above the bearing to an eccentricposition forthe turntable of the wheel, enabling the wheel to shift around with the wind without the use of a tail-vane and it also consists of improved contrivances for regulating the wheel to the force of the wind, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an elevation of the will as seen when looking from the windward side. Fig. 2 is a horizontal section of the wheel andtop view of the rest, showing the position of the wheelwhen thewind is still orblowing lightly. Fig. 3 is a similar view, showing the position of the wheel when it is turned around edgewise to the wind; Fig. 4, a detail showing the supporting tubeand arm in part and in section and the weighted regulating-lever in side elevation. Fig. 5 is a detail of the connectingrod for the crank, and Fig. 6 represents aportionof the .upright supporting-tube in sectional elevation.

For the turn-table device I propose to cmi ploy an upright tube, a, fixed in suitable bearings, b c, in the upperpart of the tower d, with the portion above the bearings bent at e eccentrically to the rest, and carrying a horizontal arm,f, at the top, extending a suitable distance from it, for carrying the wheel 9 in a vertical plane with its shaft radial to the tube when the wheel is at rest in the still air or working lightly. The eccentric construction of the supporting-tube enables the wheel to be shifted around as the wind shifts by the direct action of the Wind on it, and thus avoids the need of a tail-vane.

For varying the angle of the Wheel to the wind as the power of the wind increases, I mount the crank-shaft h in a bearing-plate, 'i, that is pivoted at j to the outer end of the arm f, and has a short arm, is, extending from the the wheel to swing toward the position of Fig, 3, where it feathers the wind, so as to bein-* operative thereby.

The lever at has a verticalarm, a, rising over the mouth of the upper end of the tube a, and having a rod, 0, connected to it, which extends down through the tube for being used to pull the wheel around out of the wind when it is to be stopped, said rod being connected to the arm by a kind of ball-joint 19, allowing the lever to vibrate. The rim q otthe wheel is made to touch the tube a at the bend 6, when swung out of the wind, to stop the rotation of the wheel by the friction.

g The armfhas a branch, t, along which the bearing-plate i traverses for support whenthe wheelswings on the pivot j. The connecting-rod a has oval or ball boxes, to, for connection with the crank, so as to allow the crank to swing as above described, and the lower end of the rod is connected by a ball-joint, a", with an arm, 7, that extends into the tube a through a slot in its side, and is swiveled to the upper end of the working-rod z. The rod 0 passes through the center of the swivel-joint.

The bent tube makes a simple and substantial turn-table, and the regulatingapparatus is simple, cheap, efficient, and durable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A wind-wheel mounted on a bent upright tube a for a turn-table, substantially as de-' scribed.

2. The shaft of a wind-wheel, mounted on a bearing-plate, i, pivoted to the supporting-arm at j, and connected by arm is and rod l with a l weighted regulating-lever, m, substantially as described.

3. The weighted regulating-lever m, having the pivoted wheel-shaft bearing connected to it, as set forth, and being arranged with relation to the turn-table axis, and having the stop-rod 0 connected to it, substantially as described.

4. The combination of supporting-tube a, arm f, pivoted wheel-shaft bearing i, and weighted regulating-lever m, substantially as described.

5. The combination of armf, branch 15, bearing-plate z, wheel-shaft h, pivot arm k, rod l, weighted lever on, and the supporting-tube a,

substantially as described.

. 6. The Wheel-shaft h, mounted on shifting bearing-plate i, and being connected with the rod 2 by the rod u, having oval boxes to for the crank and ball-joint,- connection as with the [5 arm y, said arm being swiveled to rod z, substantially as described.
